The first generation of electronic computers were those implemented using vacuum tubes.
vacuum tubes
first generation computers were not fast and were less reliable.
generations of computersThere are actually FIVE generations of computers.The first generation of electronic computers were made of vacuum tubes and they were big as a room.
The Five Generations of Computers were all not exact and some overlap in technologies exist. And all of the 5 generations of computers are sometimes useful in providing a general perspective of some of the advancements in computing technology.
The first three generations of computer technology:vacuum tubetransistorICAll tended to be large and expensive.The microcomputer was the first generation of computers small & inexpensive enough for everyone to have if they wanted one.
The term "generations of computers" refers to the classification of computers based on technological advancements and innovations over time. Each generation represents a significant leap in technology, encompassing changes in hardware, software, and architecture, from the early vacuum tube-based machines (first generation) to modern microprocessor-based systems (fifth generation). These generations highlight the evolution of computing capabilities, efficiency, and user interfaces, reflecting how computers have become more powerful and accessible.
by technology through the first 3 generations, after that there is some disagreement.
5 Generation of Evolution of computers:1. First Generation (1940-1956) Vacuum Tubes2. Second Generation (1956-1963) Transistors3. Third Generation (1964-1971) Integrated Circuits4. Fourth Generation (1971-Present) Microprocessors5. Fifth Generation (Present and Beyond)ArtificialIntelligence.
